Free for every Substrate 2 customer. Sanctions Monitor is included at no additional charge — any valid AlgoVoi suite licence unlocks it. There is no separate purchase.

​
What it is

Point-in-time screening (Compliance Gate) confirms a counterparty is clean now. Designations change — someone you transacted with last month can land on OFSI / OFAC / EU tomorrow. Sanctions Monitor keeps a watchlist, re-screens it on every sweep, and emits a Falcon-1024-signed delta receipt the moment a verdict changes. That timestamped, offline-verifiable receipt is exactly the ongoing-monitoring evidence an MLRO or supervisor wants — and it carries no PII: only subject_ref = sha256(network:address). It runs as a self-contained appliance (deploy one container) with the watchlist post-quantum encrypted at rest, and it completes the suite’s compliance-receipt family: Compliance Gate (point-in-time) -> Travel Rule (FATF R.16) -> Sanctions Monitor (ongoing).

Delta receipts on change

A signed receipt fires only when a verdict changes — newly_hit, cleared, escalated, de-escalated. The change, signed and timestamped, is the evidence.

No PII

Receipts reference a counterparty only as sha256(network:address). Hand a supervisor the proof a status changed, not the customer’s identity.

Post-quantum at rest

The watchlist’s only identifying data (the counterparty address) is ML-KEM-1024 + AES-256-GCM encrypted on disk; verdicts, timestamps and signed receipts are non-PII and stored in clear.

Bring your own screener

The same screener you run for point-in-time (the AlgoVoi OFSI/OFAC/EU cache, a commercial feed, your own) plugs straight in. The monitor ships no sanctions list.

​
What you get

  • Ongoing-monitoring evidence, on demand. A signed, timestamped record of when a counterparty’s status changed and that you caught it — the artifact UK MLR 2017 / EU AMLD ongoing monitoring expects.
  • No PII to retain. The evidence is content-addressed; the identifying address is encrypted at rest, post-quantum.
  • Turnkey. One container with the watchlist on a volume. It sweeps on a schedule, persists across restarts, and exposes a small loopback API to add subjects and pull receipts.
  • Substrate 2-bound. Every delta receipt folds into the broader Substrate 2 evidence chain.

​
How it works

StepWhat happens
WatchAdd a counterparty; it is stored content-addressed (subject_ref), the address post-quantum-encrypted at rest.
SweepOn every cycle the appliance re-screens the whole watchlist via your screener. The first sweep sets a silent baseline.
DetectWhen a verdict changes, a Falcon-1024-signed delta receipt is emitted (newly_hit / cleared / escalated / de-escalated).
VerifyAnyone confirms a receipt offline from the monitor’s public key alone — no PII in the receipt.

​
Cryptography

  • No-PII receipts. The only reference to a subject is sha256(network:address).
  • Post-quantum, both axes. Delta receipts are Falcon-1024 signed (NIST Level 5, offline-verifiable); the at-rest watchlist is ML-KEM-1024 + AES-256-GCM encrypted — an exfiltrated database leaks no counterparty identities without the ML-KEM secret.
  • Content-addressed + canonical. canon_version: jcs-rfc8785-v1; receipts verify byte-identically anywhere.

​
Who it’s for

  • VASPs, PSPs and exchanges that must evidence ongoing sanctions monitoring, not just onboarding.
  • Compliance / MLRO teams that need a provable trail of status changes without retaining PII.
  • Anyone running point-in-time screening who wants the same screener to power continuous monitoring.

Get Sanctions Monitor

Sanctions Monitor is included free for every Substrate 2 customer. It ships as a deployable appliance (one container, watchlist on a volume); we provide the gated download and help you point it at your screener and set the sweep cadence. It pairs with Compliance Gate (the verdict) and Travel Rule (FATF R.16) as a complete compliance-evidence story.
